Ítem Technology-Independent Demonstrator for Testing Industry 4.0 Solutions(IEEE, 2022-07) López, Alejandro; Sakurada, Lukas; Leitao, Paulo; Casquero, Oskar; Estévez, Elisabet; De la Prieta, Fernando; Marcos, MargaCyber-Physical Systems (CPS) are devoted to be the main participants in Industry 4.0 (I4.0) solutions. In recent years, many authors have focused their efforts on making proposals for the design and implementation of CPS based on different digital technologies. However, the comparative evaluation of these I4.0 solutions is complex, since there is no uniform criterion when it comes to defining the test scenarios and the metrics to assess them. This paper presents a technology-independent CPS demonstrator for benchmarking I4.0 solutions. To that end, a set of testing scenarios, Key Performance Indicators and services were defined considering the available automation cells setup. The proposed demonstrator has been used to test an I4.0 solution based on a Multi-agent Systems (MAS) approach.Ítem Towards the generic integration of agent-based AASs and Physical Assets: a four-layered architecture approach(IEEE, 2021-07) López, Alejandro; Casquero, Oskar; Estévez, Elisabet; Leitao, Paulo; Marcos, MargaThe I4.0 Component is a key concept of the Platform Industrie 4.0 initiative. The I4.0 Component is made up of an asset performing services and an Asset Administration Shell (AAS) representing the asset in the system. I4.0 Components must meet the requirements of interoperability, identification, representation, information management, integration, and asset management. Industrial agents are a suitable approach to implement I4.0 Components since they meet these requirements and provide additional features such as distributed decision-making capabilities. Nevertheless, the development of generic approaches for the integration of AASs and assets is not straightforward due to the diversity of physical assets in the factories. This paper proposes a four-layered architecture for the implementation of I4.0 Components based on industrial agents, two in the agent-based AAS and the other two in the physical asset. The division into layers enhances the separation of concerns, encapsulating the different integration aspects at different abstraction levels. This approach is complementary to the standard IEEE 2660.1-2020 on recommended practices for industrial agents, which focuses on the deployment of the interface between the agent and the physical asset. As a proof of concept, the proposed architecture will be applied for the integration of a software agent and a robot from an assembly cell, aiming to create an I4.0 Component.
